Chapter 2

System Safety

Chapter 2: System Safety

2-1 Overview

This chapter provides a quick setup checklist to get your chassis up and running.

Following the steps in the order given should enable you to have your chassis set up and operational within a minimal amount of time. This quick setup assumes that you are an experienced technician, familiar with common concepts and terminology.

2-2 Warnings and Precautions

You should inspect the box the chassis was shipped in and note if it was damaged in any way. If the chassis itself shows damage, file a damage claim with carrier who delivered your system.

Decide on a suitable location for the rack unit that will hold that chassis. It should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated.

You will also need it placed near at least one grounded power outlet. When configured, the SC745 chassis includes one power supply. "R" models (for example the SC745TQ-R800B chassis) include a redundant power supply and require two grounded outlets.

2-3 Preparing for Setup

The SC745 chassis includes a set of rail assemblies, including mounting brackets and mounting screws you will need to install the systems into the rack. Please read this manual in its entirety before you begin the installation procedure.

2-1


2-4 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm and the SC745 from damage:

•

Be aware of the locations of the power on/off switch on the chassis as well as the room’s emergency power-off switch, disconnection switch or electrical outlet. If an electrical accident occurs, you can then quickly remove power from the system.

•

Do not work alone when working with high-voltage components.

•

Power should always be disconnected from the system when removing or installing main system components, such as the serverboard, memory modules and the DVD-ROM (not necessary for hot-swappable drives). When disconnecting power, you should first power-down the system with the operating system and then unplug the power cords from all the power supply modules in the system.

•

When working around exposed electrical circuits, another person who is familiar with the power-off controls should be nearby to switch off the power, if necessary.

•

Use only one hand when working with powered-on electrical equipment. This is to avoid making a complete circuit, which will cause electrical shock. Use extreme caution when using metal tools, which can easily damage any electrical components or circuit boards they come into contact with.

•

Do not use mats designed to decrease electrostatic discharge as protection from electrical shock. Instead, use rubber mats that have been specifically designed as electrical insulators.

•

The power supply power cord must include a grounding plug and must be plugged into grounded electrical outlets.

•

Serverboard battery: CAUTION - There is a danger of explosion if the onboard battery is installed upside down, which will reverse its polarities. This battery must be replaced only with the same or an equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

2-2

Chapter 2: System Safety

•

Handle used batteries carefully. Do not damage the battery in any way, a damaged battery may release hazardous materials into the environment. Do not discard a used battery in the garbage or a public landfill. Please comply with the regulations set up by your local hazardous waste management agency to dispose of your used battery properly.

•

DVD-ROM laser: CAUTION - This server may have come equipped with a

DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous radiation exposure, do not open the enclosure or use the unit in any unconventional way.

2-5 General Safety Precautions

•

Keep the area around the chassis clean and free of clutter.

•

Place the chassis top cover and any system components that have been removed away from the system or on a table so that they won’t accidentally be stepped on.

•

While working on the system, do not wear loose clothing such as neckties and unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling fan.

•

Remove any jewelry or metal objects from your body, which are excellent metal conductors that can create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present.

•

After accessing the inside of the system, close the system back up and secure it to the rack unit with the retention screws after ensuring that all connections have been made.

2-6 System Safety

Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. An electrical discharge is created to neutralize this difference, which can damage electronic components and printed circuit boards. The following measures are generally sufficient to neutralize this difference before contact is made to protect your equipment from ESD:

•

Do not use mats designed to decrease electrostatic discharge as protection from electrical shock. Instead, use rubber mats that have been specifically designed as electrical insulators.

2-3


•

Use a grounded wrist strap designed to prevent electrostatic discharge.

•

Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.

•

Touch a grounded metal object before removing any board from its antistatic bag.

•

Do not let components or PCBs come into contact with your clothing, which may retain a charge even if you are wearing a wrist strap.

•

Handle a board by its edges only; do not touch its components, peripheral chips, memory modules or contacts.

•

When handling chips or modules, avoid touching their pins.

•

Put the serverboard and peripherals back into their antistatic bags when not in use.

•

For grounding purposes, make sure your computer chassis provides excellent conductivity between the power supply, the case, the mounting fasteners and the serverboard.

5-9 Power Supply

Depending on your chassis model, the SC745 chassis has an 800, 920 or 1200

Watt power supply. "R" model chassis feature a second redundant power supply.

This power supply is auto-switching capable. This enables it to automatically sense and operate at a 100v to 240v input voltage. An amber light will be illuminated on the power supply when the power is off. An illuminated green light indicates that the power supply is operating.

Power Supply Failure

In redundant power supply models, the system automatically switches to the second power supply when the first fails. If your system has only one power supply, the system shuts down in the unlikely event of a power failure.

Replacing the Power Supply

1. Power down the server and unplug the power cord. If your chassis includes a redundant power supply (at least two power modules), you can leave the server running and remove only one power supply.

2. Push the release tab on the back of the power supply.

3. Pull the power supply out using the handle provided.

4. Replace the failed power module with the same model.

5. Push the new power supply module into the power bay until it clicks into the locked position.

6. Plug the AC power cord back into the module and power up the server.

Rack Installation

Chapter 6: Rack Installation

6-1 Overview

This chapter provides a quick setup checklist to get your chassis up and running.

Following these steps in the order given should enable you to have the system operational within a minimum amount of time.

6-2 Unpacking the System

You should inspect the box the chassis was shipped in and note if it was damaged in any way. If the chassis itself shows damage you should file a damage claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold your chassis. It should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. You will also need it placed near a grounded power outlet. Be sure to read the Rack and Server Precautions in the next section.

6-3 Preparing for Setup

The box your chassis was shipped in should include two sets of rail assemblies, two rail mounting brackets and the mounting screws you will need to install the system into the rack. Please read this section in its entirety before beginning the installation procedures

Choosing a Setup Location

•

Leave enough clearance in front of the rack to open the front door completely

(25 inches).

•

Leave approximately 30 inches of clearance in the back of the rack to allow for sufficient airflow and ease in servicing.

•

This product is to be installed in a Restricted Access Location only, (dedicated equipment rooms, service closets and others).

Warnings and Precautions!

!

•

Rack Precautions

Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting on them.

•

In single rack installation, stabilizers should be attached to the rack.

•

In multiple rack installations, the racks should be coupled together.

•

Always make sure the rack is stable before extending a component from the rack.

•

You should extend only one component at a time - extending two or more simultaneously may cause the rack to become unstable.

•

General Server Precautions

Review the electrical and general safety precautions that came with the components you are adding to your chassis.

•

Determine the placement of each component in the rack rails.

before you install the

•

Install the heaviest server components on the bottom of the rack first, and then work up.

•

Use a regulating uninterruptible power supply (UPS) to protect the server from power surges, voltage spikes and to keep your system operating in case of a power failure.

•

Allow the hot plug hard drives and power supply modules to cool before touching them.

•

Always keep the rack's front door and all panels and components on the servers closed when not servicing to maintain proper cooling.

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the ambient temperature of the room. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer’s maximum rated ambient temperature (Tmra).

Reduced Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connections other than the direct connections to the branch circuit (i.e. the use of power strips, etc.).
